IMPROVEMENT IN APPARATUS POR MIXING, HEATING", .AND COOLING SUBSTANCES.

The Schedule referred to in these Letters Patent and making p'art of thesame,

'To-all whom tt may concern Be it known that LMELCHIOR Notons,offhrankfort-on-the-Main, in the Kingdom of Prnssia,have inventeda newand improved Apparatus for Heating,

;O ooling, and Mixing Solid or' Liquid Materials; and vI do herebydeclare the following to be a full, clear,

and exact description thereof, which will enable those skilled in theart to make and. use the same, reference being had to the accompanyingdrawing forming` part of this specification, in which drawing- K vFigure l represents a longitudinal vertical section of this invention.

Figure 2 is a side view of the same.

Figure 3 is a plan. or top view of the trough, which forms the bearingsof the working parts of my apparatus. 4

Figure 4 is a transverse vertical section of the apparatus, in a largerscale than` the previous ligures.

Figure 5 is au end view of the same in a smaller' scale thanthe previousfigures. y

Figure 6 is a transverse section of the trough and cover.

Figure 7 is a detached section of the tubular scoops. v

Figure 8 is a detached section'of the' hollow shaft, as used fortreatingsolid materials.

Similar letters indicate corresponding parts.

This 'invention relates to an apparatus, ywhich consists of tubularscoops, capable of taking up the materials lto be treated, and oftransmitting the same into a hollow shaft, from which they escape into ailat spiral, mounted on said shaft, and revolving with the saine, andprovided with perforated heads, in such a manner that the material,while passing throughthe spiral, can be exposed to a eurrent of cold orhot air, o'r steam, and it can thus be rapidly cooled, heated, or dried.

By arranging two or more sets of tubular scoops on` divided bytransverse partitions q fr, and a longitiuli-v ual partitition, s, (seefig. 3,) in four compartments, III, IV, V andVl.

lhe ends of the `trough B form the bearings for a hollow shaft, b, onwhich is mounted a flat spiral, C, the heads D of which are perforatedand provided with spiral ribs on their inner surfaces, which form thesupports for the dat spiral O. In practice, the flat spiral Gis producedof a series of sheet-metal plates secured to the spiral ribs.

The transveise partitions q and '11 are cut outto retceive the heads.

lo one end of the trough B is attached a reservoir, which maybe dividedby one or more vertical par-I titions= in two (or more) compartments, III, which are intended to receive the materia-ls to'be treated.

These compartments are situated under the end of the shaft b, on whichare mounted the' tubular scoops al c, one set for cach compartment.-

These scoops communicate with the inte-rior of the shaft b, and as thisshaft revolves, the material or materials contained in the compartmentsI II are vtaken up and transmitted into the hollow shaft b, whichcommunicates, through one or more long narrow apertures, bi, with theinner end of the fiat spiral C.

As this spiral revolves with theshaft b, the material or materialstransmitted to it pass gradually out Vthrough said spiral, and aredeposited in theeompartmeut III ofthe trough l.

'-lhe bottom of this compartment is provided with an aperture, which canbe opened or closed by means of a plate, t.' l

rIhe compartment lll communicates, through an opening, t', (seefig.,3,)vwith the compartment IV, and an opening, 7.', leads from thislatter compartment into the compartment V, which communicates, throughan opening, l, with the compartment VI.

The compartments IV and VI are furnished with nipples f and y, thenipple fto communicate with an air-forcing apparatus, and the nipple gto communi- 'cate with a discharge-pipe. v

lhe compartments l and II are provided with sup-- ply-openings m and n.,and with adjustable overflow' pipes o Aand p, which serve to keep auniform supply ofliqnids in said compartmentsfif the apparatnsis to outthrough the pipe y. ln this case the bottoni plate tis removed, toallow'the cured or dried materials to discharge. v

For the purpose of heating or cooling liquids, the liquids are made topass through the spiral C, as above, while hot or cold air is circulatedthrough the trough l. rlhe bottom plate tis fastened down, -and theliquid discharging from the spiral passes through the trough B, asindicated by the arrows in fig. 3, and'V Y -discharges through a pipe,71.

For the purpose of mixing fluid or solid materials, the materials to bemixed are -introduced into the compartments I 1I, audthence Inadeto passthrough the apparatus, as above stated;

In condensing gaseous substances these substances are. passed into theapparatus through the pipe f, while the water required to absorb them ispassed through the-spiral C. 1

'lo prevent powdered or granulated materials passingr through theapparatus from clogging in the interior of the shaft b, the passage insaid shaft may be made tapering, as shown in tig. 8. p

What I elaimas new, and desire to 'secure by Letters Patent, is

l. .lhe tubular scoops d, in combination with the hollow lshaft b anddrum C, substantially as described.

2. The spiral G, with perforated heads D, in com,-

bination with the hollow shaft b and trough B, substantially as setforth. c l

3. '.lhe compartments III, IV, V, VI, in the trough 13, in combinationwith the spiral G, hollow shaft l),

and scoop d, substantially as described.

4. The combination of two or more sets of tubular scoops, l e, with thehollow shaftb and spiral G, substantially as set forth.
